摘要：

采用季戊四醇、三氯氧磷和间苯二酚为反应物，合成了新型添加型阻燃剂：间苯二酚-双[二（季戊四醇）]磷酸酯（RBPP），通过元素分析、FTIR和¹H NMR等测试技术表征了标题化合物的结构，结果表明，所合成的标题化合物的结构与预期的结构一致。热失重分析结果证明，RBPP质量损失5%时的温度在350.0 ℃，600 ℃残炭率高达57.4%，具有较高的热稳定性能。阻燃性能实验证明，E-51环氧树脂中添加质量分数为15.2%的RBPP时，极限氧指数达31.8%，UL-94为V-0级。

Abstract:

A novel phosphorus-containing flame retardant，resorcinol bis[di(2,6,7-trioxa-1- phosphabicyclo [2.2.2]-octane-1-oxo-4-hydroxymethyl)] phosphate（RBPP）was synthesized from pentaerythritol，phosphorus oxychloride and resorcinol. The title compound was characterized by elemental analysis，FTIR，and ¹H NMR. The results showed that the structure of the title compound was consistent with expectation. Thermogravimetry（T_g）investigation on thermal stability of RBPP showed that mass loss of 5% was at about 350 ℃ and residue at 600 ℃ was as high as 57.4%. The limiting oxygen index（LOI）value coulds reach 31.8% and flame retardancy was UL-94 V-0 when mass fraction in E-51 epoxy resin was 15.2%.
